Answer:
C. 195ft²
Step-by-step explanation:
First find the area of the semi-circle:
A = πr²
The radius is 5 (half the diameter)
Plug in the numbers using 3.14 for pi:
A = 3.14(5)²
A = 78.5
Halve the area so you get the area of half a circle:
78.5/2 = 39.25
Now find the area of a trapezoid:
Plug in the numbers:
A = 10+16/2*12
A = 156
Lastly, add the area of the semi-circle and trapezoid together:
39.25+156 = 195.25ft²
